A wealth of research has revealed that psychopathy and psychopathic personality traits are associated with criminal involvement. Comparatively less research, however, has examined whether psychopathic personality traits influence economic outcomes in adulthood. The current study addresses this gap in the literature by analyzing data drawn from the National Longitudinal Study of Adolescent Health. The results of the analyses indicate that psychopathic personality traits are negatively related to a number of economic outcomes, including household income and employment history measures. Individuals with high levels of psychopathic personality traits were found to have lower household incomes and to be fired more frequently than individuals with lower levels of psychopathic personality traits. Unexpectedly, psychopathic personality traits were also found to be negatively associated with household debt. There was also some evidence that the effect of psychopathic personality traits was moderated by intelligence in the prediction of household income. We discuss what these findings mean for the psychopathy and economics literatures. 相似文献

More than 2 billion people use Facebook, Instagram and Twitter combined. Considering that astonishing figure, it's safe to assume that many college student‐athletes use social media. 相似文献

The article addresses some of the key issues that are raised for researchers engaging with counterterrorism police officers and initiatives, when undertaking research. A significant area to explore in this context is, in fact, the issue of relationships with counterterrorism police officers who may themselves directly have been covert police officers in the past and/or who may be continuing in their current, apparently more open, role (wittingly or otherwise) as agents of broader state strategies of exploiting trust for intelligence-gathering purposes. This article suggests that it is important for researchers to understand that working within the counterterrorism field involves degrees and shades of risk in the service of trust-building, sensitivity and the empowerment of communities, and that researchers themselves can (wittingly and unwittingly) be part of wider strategies instigated by security-minded individuals or groups of counterterrorism police officers. Reflecting upon the research that we have undertaken individually and collectively over the last number of years, in the light of the most recent spate of allegations about counterterrorism police officers infiltrating activist and political protest groups, having sexual relationships, and indeed, on occasion, children, with women whilst undercover and of potentially working to entrap vulnerable individuals into planning terrorist acts, this article raises questions around trust, credibility, legitimacy, the prevalence and near unavoidability of dysfunctional agendas and the implications of all of the above for community-based approaches to counterterrorism. 相似文献

The use of chemical enhancement techniques on porous substrates, such as fabrics, poses several challenges predominantly due to the occurrence of background staining and diffusion as well as visualization difficulties. A range of readily available chemical and lighting techniques were utilized to enhance footwear impressions made in blood, soil, and urine on dark and patterned fabrics. Footwear impressions were all prepared at a set force using a specifically built footwear rig. In most cases, results demonstrated that fluorescent chemical techniques were required for visualization as nonfluorescent techniques provided little or no contrast with the background. Occasionally, this contrast was improved by oblique lighting. Successful results were obtained for the enhancement of footwear impressions in blood; however, the enhancement of footwear impressions in urine and soil on dark and patterned fabrics was much more limited. The results demonstrate that visualization and fluorescent enhancement on porous substrates such as fabrics is possible. 相似文献

ABSTRACTThe theory of threshold concepts has become a popular way to describe the difficulties students face when trying to grasp fundamental ideas in a discipline. In law authors have suggested a range of concepts as thresholds. However these suggestions conflict with each other, and have not emphasised the way in which students repeatedly encounter such thresholds. Using variation theory and the concept of knowledge capability this article suggests that the Threshold Capability Integrated Theoretical Framework may be a way to resolve those differences and to highlight the ongoing nature of liminality in becoming a professional. Students may grasp initial threshold concepts early in a degree or subject, develop the ability to manipulate and use them in a variety of settings towards the end of the degree, and develop a lifelong professional ability to use them in diverse settings after graduation. Law students, lawyers and indeed law teachers may be best seen as in a constant state of learning. The uncertainty that goes with that learning is to be embraced, and encouraged as part of the way we teach law. 相似文献
